Looking at those codes you have a failure in the CAN bus. You would need to start with an oscilloscope connected to the CAN bus to see what the signal looks like. At the moment it is either missing or very corrupt. Then isolate each component on the CAN bus one at a time until the signal returns or is correct. Then you can repair or replace that part. I would start with the steering column module as there are numerous codes for it, however MB has the module on both the high and low CAN networks, so it makes it harder to test. That is, however, where I would look first. It might be possible to unplug the connector on the steering module and then erase the codes and see which ones return. The problem with that is MB likes to report the loss of signals as well as signal failures so you can end up with other codes as well. That is where using a scope to test works better as it can test with things connected and isolate the data problem.
